Standard Measurement System (US Customary) Converting From One Unit of Measurement to Another
What happens if you are given a measurement in one unit,
but need to use it in another?
In order to find out, you would need to do something called converting. You need to convert the unit of cups to the unit of pints.
For example, you are baking cupcakes, and the recipe calls for 4 cups of oil. The bottle of oil says that it contains 3 pints. How do you know if you have
enough oil?

So how many cups are there in 3 pints?
2 cups x 3 pints = 6 cups in 3 pints

Slide 10 / 115
When converting measurements, use your arms to help you.
We can spread our arms out wide to show that something is bigger.
We can fold our arms in a hug to show that something is smaller.
To convert a smaller unit to a larger unit, we divide the
amount.
To convert a larger unit to a smaller unit, we multiply the
amount.
Converting Measurement
Slide 11 / 115
Troy has 6 popsicles that are 5 in long each. If he places them all in a line, how
many feet would they be?
5 in + 5 in 5 in 5 in 5 in 5 in+ + + += 30 in
How many feet are 30 in?
We are going from inches to feet, so we are converting a smaller unit to a larger unit.
Therefore, we need to ________.
30 in X or _____(# of inches in a foot)
= ___ ft ___ in
Conversions
Slide 12 / 115
I bought a set of 4 glasses from the market. A glass weighs 8 ounces. How many pounds does the set weigh?
We are going from ounces to pounds so we are converting a smaller unit to a larger unit.
Therefore, we need to ________.
32 oz X or _____
(# of oz in a lb)= ___ lbs
Another example:
Find the total ounces: ___ oz x __ glasses = ___ oz.
Conversions
Slide 13 / 115
How can we write measurements using fractions?
Think about what half a foot is in inches.
If a foot is 12 in, then 1/2 a foot 12 ÷ 2.
So, half a foot is 6 in.
How many inches is a foot and a half?
A foot and a half is 12 x 1.5.
So, a foot and a half is 18 in.How many feet are there in 30 inches?
30 ÷ 12 = 2.5 So, there are 2 1/2 feet in 30 inches.

Sample Student Response:
The volume of the prism is 60 cubic units because 4 x 5 x 3 = 60.
The dimensions of a new right rectangular prism that has 20 fewer unit cubes than the original prism could be 4 units wide by 5 units tall by 2 units deep. I determined these dimensions by recognizing that each layer of the original prism that is 4 units wide by 5 units tall by 1 unit deep has a volume of 20 cubic layers. So I took one of these layers away from the original prism.
